Tether: A Ferris Sweep Unibody Case

prusaprinters

<h4>Instructions</h4><p>I printed my case at .2mm layer height with 15% infill and it works well. <strong>Make sure to align the center piece's flat face with the build plate </strong>as I have not yet figured out Fusion360 well enough to change this by default. The left and right pieces should be good to go and will just need centered on your build plate.</p><p>When finished printing the pieces should friction fit together.</p><h4>Background</h4><p>This is version 1 of an idea I had for a split keyboard case that can easily change between split use and unibody use, which I have named “Tether.” Version 1 was designed for just my keyboard (Ferris Sweep Half Swept). But I would like to get feedback and iterate on the design, as well as make them for more than just the Sweep Half Swept. So please tell me what you think.</p><p>This first version doesn’t secure the PCB in any way and the case itself isn’t meant to come apart, so it isn’t truly a “convertible case” yet.&nbsp;</p><p>Since my keyboard switches are directly soldered, I clipped all the excess pins off the bottom of my PCB and used double sided tape to attach a mouse pad material to the bottom of the PCB. This makes for a more pleasant experience (in my opinion) than adhesive rubber feet as you get more grip and more surface area means better adhesion.</p><p>So the keyboard itself just sits in the case and isn’t attached in any way. When I want to use it as a split, I pull the halves out of the case and use it like normal. When I want to use it as a unibody I pop the halves into the case and gravity works just fine to keep them there. There is no wobble. In theory the case should work fine for anyone using a PCB only (caseless) Ferris Sweep with the same dimensions of the Half Swept PCB.</p><p>The case is printed in 3 pieces so that the middle piece’s length could be adjustable (by using different length pieces). I have not yet modeled different length pieces. The pieces are friction fit together and are pretty secure.</p><p>What I would like to achieve eventually is a fully convertible case, where the PCB is attached to the case halves and the center piece that joins them is attachable and meant to be removed and replaced regularly. This is my first foray into 3D modeling so I started simple. Please let me know if you have any feedback.</p><h4>&nbsp;</h4>
